There are very few that crack jokes as much as i do, and my sense of humor is dark. Yet the ideal of a joke is to make people laugh, not to be insulting to anyone or group. I find no humor in that. Anyone that defends such things is as bad as the individual that throws it out there.There are instances where joking at groups in a harmless way, is okay. but everyone including those in group knows it's a joke. This is one we used to tell in the army, as an example; "Did you hear about the Polish secret agent that got injured badly? Yes, they burned their lips badly in an attempt to blow up a car using its tailpipe." I was stationed in Poland for a short time, some of the greatest people ever, and it is so silly, everyone knows it is not mean spirited. I heard this one constantly about us while there, "Do you know why Americans are of no real danger in an operation? Cause all you have to do is throw a $20 dollar bill to distract them as you make your escape." Again it is silly and nothing is meant by it, we all laughed at it. That picture from Shreddit is not funny, you will find a great deal stuff like that on there.
